XLPE Compound

XLPE Cross-linked Polyethylene Materials

XLPE stands for cross-linked polyethylene. It is an advanced material modified through chemical or physical processes. It is a polymer whose properties are enhanced by the formation of cross-linked structures between polyethylene molecules. The molecular weight of XLPE significantly influences its mechanical strength, thermal stability, and resistance to environmental stress cracking. XLPE materials belong to the category of cross-linked polyolefins (XLPO) and can be collectively referred to as XLPO.

It is a commonly used raw material in the manufacture of wires and cables for sectors such as new energy, photovoltaics, and rolling stock. In cable applications, XLPE-insulated cables are highly favored for their excellent electrical insulation properties and ability to withstand harsh environments.

It features flame retardancy, UV resistance, mold resistance, and high-temperature resistance. Its resistance to environmental stress cracking ensures high durability, making it suitable for long-term applications.

Currently, ANGREEN's XLPE product series primarily includes (electron-beam) irradiation cross-linked polyethylene and (silane-cured) silane self-cross-linking polyethylene.

Based on temperature ratings, they can be classified as follows:

105°C XLPE cable sheathing/insulation materials

125°C XLPE cable sheathing/insulation materials

150°C XLPE cable sheathing/insulation materials

Key Characteristics of ANGREEN XLPE materials include:

Heat resistance: XLPE supports a long-term operating temperature of 90°C, a short-term overload temperature of 130°C, and a short-circuit temperature of 250°C, making it suitable for high-temperature environments.

Electrical properties: It possesses high dielectric strength and low dielectric loss, effectively preventing current leakage and ensuring the safe, stable operation of electrical equipment; it is highly suitable as an insulation material for extra-high voltage (EHV) cables.

Chemical stability: It exhibits excellent resistance to acids, alkalis, and chemical corrosion, making it suitable for harsh environments. Compared to high-density polyethylene (HDPE), XLPE offers superior chemical corrosion resistance and resistance to stress cracking. Mechanical Properties: High tensile strength and impact resistance, capable of withstanding external forces.

Thermal Properties: Low thermal conductivity and a low coefficient of thermal expansion help minimize heat loss and thermal stress.

Irradiation Cross-linked Polyolefin XLPO Cable Material

XLPO (cross-linked polyolefin) is a thermosetting material that includes polymers of various olefin monomers, such as ethylene, propylene, etc., and its performance is improved through the cross-linking process. XLPO material is particularly important in cable insulation because it does not contain halogens and therefore does not release toxic gases when burned, which has significant advantages in terms of safety and environmental protection.

Halogen-Free Irradiated XLPE Cable Material

LSZH irradiated XLPE cable material is halogen-free, heat-resistant and environmentally friendly. Designed for power, control and instrument cables, it has high tensile strength, excellent electrical insulation and chemical resistance, ensuring safety in critical environments such as subways, tunnels and nuclear power plants.
